Moon Iron & Steel commissions SMS group with the supply of a complete minimill

Oman-based Moon Iron & Steel Co. S.A.O.C. (MISCO) has contracted SMS group to build a new rebar production minimill. The new steel complex, the first of its kind in the Middle East region, is being built in Sohar Industrial Estate, Sultanate of Oman, and operation will commence in 2018.The steelworks, featuring a 140-t AC electric arc furnace, a 140-t ladle furnace, and a five-strand continuous billet caster, is able to produce 1.2 million tons per year of billets, out of which 1.1 million tons per year are rolled into rebars from eight to 40 millimeters. The fully-continuous rolling line is equipped with fourteen stands arranged in horizontal and vertical configuration followed by two high-speed finishing blocks with six “V” type mill stands each. The roughing and intermediate trains are designed as HL housingless stands. The “V” blocks are specifically designed for highly efficient and productive finish-rolling of rebars up to 50 meters per second. The high-speed delivery system HSD® enables to roll material at speeds of 41 meters per second.

“Paramount among the requirements were the lowest possible energy consumption as well as minimal emissions”, said Mr. Sasikumar Moorkanat, MISCO CEO. The response to this challenge is SMS group developed CMT® mill (Continuous Mill Technology). CMT® has taken the basic minimill concept one step forward: The direct linking of the rolling mill with the steelworks guarantees short distances. Rolling takes place without time lag by exploiting the casting heat. CO2-intensive reheating furnaces can be dispensed with. Instead of an oil- or gas-fired furnace, an inductive heating system is employed. This system does not reheat the billets but only equalizes the temperature profile. The induction heater gives you perfect control of the starting temperature for the rolling mill – according to the billet speed. This solution requires much lower investment costs. By eliminating the complete reheating stage, energy costs and the impact on the environment are markedly reduced.

Furthermore, SMS group supply covers also the complete electrical and automation package that includes Level-1 and Level-2 process control. In addition to seamlessly integrating the process functional units, with the implementation of the state-of-the-art process solutions already highlighted, the automation system will allow MISCO to meet all possible market demands with built-in capabilities for plant-wide production planning, scheduling, tracking and reporting.

Primetals Technologies to modernize flat rolling block for Böhler Edelstahl in Austria

  • Plant to be fitted with new automation and drives technology
  • Further improvements to availability and product quality
  • New technology will increase energy efficiency and cut maintenance costs
  • “RollMaster” to handle generation and management of pass schedules

Primetals Technologies has won an order from Böhler Edelstahl GmbH & Co KG (Böhler Edelstahl), a company of the Special Steel Division of voestalpine, to modernize the flat rolling block at its Kapfenberg plant in Austria. The plant will be equipped with a new drives- and automationsystem. The “RollMaster”, specially developed for long product rolling mills, will handle the generation and management of the pass schedules. The project is designed to increase plant availability, improve product quality, boost energy efficiency and cut maintenance costs. Modernization work is scheduled to take place during a one-month plant shutdown mid-2017.

The flat rolling block consists of three horizontal and two vertical stands, and produces flat bars in widths ranging from 43 to 205 millimeters and in thicknesses from 4.5 to 86 millimeters. A hydraulic drive system and a now obsolete, proprietary automation system have been in use since commissioning in 1988. Spare parts supply and adequate servicing can no longer be ensured. Böhler Edelstahl therefore decided to ask Primetals Technologies to completely modernize the automation and drives system. In previous years, Primetals Technologies has equipped the continuous rolling mill in the multiline rolling mill and the roughing stand of the blooming mill with new automation and drives technology, and supplied new drives for the six-stand HV-combination mill.

Primetals Technologies will be supplying new main and auxiliary drives with Sinamics S120 frequency converters, a new operator control and monitoring system based on Simatic PCS7, and new main gearboxes. The elimination of the hydraulic systems will reduce maintenance costs and increase plant availability which, in turn, will boost the productivity of the rolling line. Energy requirements as well as the consumption of hydraulic oil and cooling water will fall substantially. In future the “RollMaster”, specially designed for long product rolling mills, will handle the generation and management of the pass schedules. This software is the link between the production planning system and the plant automation. Primetals Technologies will also handle engineering, manufacturing, commissioning and customer training.

Böhler Edelstahl employs more than 2,000 people, and produced some 162,000 metric tons of steel in fiscal 2016. The company specializes in the production of long products and open-die forgings made of tool steel, high-speed steel, special materials and nickel-based alloys. Böhler Edelstahl GmbH & Co KG was founded in 1991 and is a wholly owned subsidiary company of voestalpine Edelstahl GmbH.

MEPS – COIL PRICES EXPECTED TO CONTINUE RISING IN NORDIC REGION

According to MEPS, business activity for hot rolled coil is stable across the Nordic region. The mills’ attempts to lift selling values were largely successful, in October. We expect that upward price pressure will be increased by the announcement of European Union antidumping measures against Chinese hot rolled coil and plate.

Consumption of hot rolled plate is quite weak. Demand from bus and truck manufacturers is good but the agricultural equipment and oil and gas sectors are not strong. Antidumping action against Chinese suppliers may introduce upward price pressure in the short term.

Western European mills report that their cold rolling schedules are full, through to the end of the year. This has helped producers in northern Europe secure increases. Delivery lead times are longer than usual.

Hot dipped galvanised material is in quite short supply. Consequently, the mills have managed to raise prices in October. Demand from car makers continues to be strong.

Purchasing activity for wire rod is slower than expected. However sellers are optimistic that demand will pick up in the near future. Producers from southern Europe have become more active in the market. Prices could slide further but no dramatic fall is anticipated.

Demand for structural sections is quite weak, for the time of year. Scrap costs are low. Beam prices continue to drop back, following the steep rise earlier in the year. Consumption by the construction sector is fair.

Consumption of rebar is reasonable. However, prices continue to fall steeply. Buyers speak of offers from new suppliers in Russia and Spain. This, combined with low scrap costs, is putting downward pressure on selling figures.

SMS group received FAC from Daehan Steel for modernizing the VCC® line in its rebar rolling mill

SMS group received the FAC from Daehan Steel Co., Ltd. for the modernization of the existing shear no. 3 in the VCC®-line (Vertical Compact Coiler) of the rebar mill in Pyeongtaek, South Korea.The modernization project involved the replacement of the switch and the scrap guiding system of the existing shear no. 3 by new equip­ment. Thanks to a newly developed high-speed switch and the upgrade of the automation system, it was possible to implement head and tail end cropping at speeds of up to 35 meters per second with­out any major modification to the adjacent plant parts. The rolling mill supplied in 2011 was originally designed for maximum cropping speeds of 15 meters per second. Due to the modernization of the VCC®-line, Daehan Steel is now able to increase the throughput to 70 tons per hour.

For this plant the new switch was constructed and delivered in just five weeks and only three days were needed for subsequent assem­bly and commissioning. The solution based on the Plug & Work principle, the reduced investment costs and a short delivery time were decisive factors for the implementation of this project.

MEPS – EU FLAT PRODUCT STEEL PRICES RISE IN OCTOBER, FURTHER INCREASES FORECAST

According to MEPS, the upward momentum in average European strip mill product prices, reported in September, continued in October. ArcelorMittal announced new target prices for fourth quarter production that are higher than current market levels. Many buyers anticipate that they may be forced to pay more when future negotiations take place. Overall consumption is relatively stable but supply is limited due to a lack of imported material from third country sources, resulting from a series of trade defence measures on both hot and cold rolled coil, together with higher prices demanded by many overseas suppliers. Delivery lead times from European mills are extending into December/January, pushing buyers to secure tonnage for the start of 2017, earlier than usual.

German demand is healthy. End-users are positive regarding business levels in 2017. Strip mill product basis values continued to rise, as a result of restricted supply and extended delivery lead times. Although a number of buyers are not convinced that the whole of the recently proposed hike can be implemented. Service centres are recouping the mill increases in their resale prices. Their stocks, especially of cold rolled and galvanised coil, are on the low side.

In France, October market activity was subdued but rising prices boosted mill order intake. Steelmakers implemented further increases, with more upward movement expected in the near term, when negotiations for the first quarter 2017 are concluded. We note much less imported material on offer. Buyers report that European mill delivery lead times are now similar to those from overseas producers.

Tight supply forced basis values up in Italy. Traditionally, the region has been particularly dependent on imports. Local steelmakers claim to be fully booked for 2016. Overall, industrial production has slowed but a number of sectors continue to recover, including automotive, mechanical engineering and tube manufacturing. Nevertheless, service centres struggle to lift their resale values in line with mill hikes. Sales are slow, as demand is mediocre.

The recent sharp fall in the pound sterling, against the euro and US dollar, resulted in significant upward movements in flat product prices during negotiations for the first quarter 2017, between UK customers and mainland European suppliers. Distributors reported better sales in October than in August/September. The majority of service centres continue to apply the mill increases and, consequently, margins are reasonably good on most products. Stocks are low due to supply shortfalls.

Belgian distributors reported improved activity in early October. It was possible to apply recent mill hikes to first half 2017 supply contracts. Steelmakers were well booked for December/January production with prices continuing on an upward trend. Imports are available from South Korean and Indian suppliers but the prices are similar to those from European sources.

Ongoing constrained supply led to higher basis numbers in Spain. Despite announcements from some steelmakers to the contrary, a number of buyers do not expect to pay more for January shipments. Distributors complain that their customers are resisting increases. Demand is stable. Competitively-priced imports are on offer from several third country sources not affected by current antidumping measures, typically Turkey, India, Egypt and Brazil. MEPS understands that a number of deals have been concluded, for arrival February 2017.

Hoa Sen Group, Vietnam, orders twin-stand cold rolling mill from SMS group

Hoa Sen Group is building a new cold rolling mill complex at Vinh City, Nghe An Province in Central Vietnam, to expand their production capacity. For this project, Hoa Sen Group has placed an order with Esmech Equipment Pvt. Ltd., an Indian joint venture company of SMS group, for the supply of a twin-stand reversing cold mill (CCM®).With this order, Hoa Sen Group is confirming their trust in plant technology from SMS group. Esmech had earlier supplied a six-high CVC® plus (Continuously Variable Crown) reversing cold mill to Hoa Sen, which has been in operation since 2015 in their plant at Phu My in South Vietnam. SMS group in Germany will provide the core technological components of the rolling mill. The total supply scope also includes an extensive X-Pact® electrical and automation package. The CCM® will be equipped with the advanced X-Shape flatness measurement and control system, level-2 automation, a system for automatic flatness control, and adaptive physical models for pass schedule calculation.

The CCM® will be designed for low-carbon steel strips with a maximum width of 1,250 millimeters and minimum final gages down to 0.11 millimeters, at an annual production capacity of up to 400,000 tons. In combination with other proven rolling technologies, SMS group’s CVCplus® technology will ensure strip production in premium quality. The six-high mill stands will be equipped with small-diameter work rolls allowing high reductions per pass. Rolling will take place at rolling speeds of up to 1,400 meters per minute. The CCM® will come with one pay-off and two reversing reels, allowing the finished coils to be removed at the entry or exit side as needed. The reversing reels will be designed to produce finished strip coils of up to 27 tons. Both tension reels will be equipped with belt wrappers for careful coiling of thin-gage strips onto the sleeves. Work and intermediate roll changing will take place automatically.

SMS group will supply the complete electrics and automation systems including levels 1 and 2. Adaptive models based on physical data, for example for providing descriptions of the strip shape, roll gap and roll setting, form the basis for optimized pass schedule designing and ideal process parameter input for the thickness, tension and flatness control systems. This enables the mill to react extremely flexibly to any changes in the rolling process and reliably achieve the required product quality. The X-Shape flatness measurement and control system ensures excellent flatness results. SMS group will supply two X-Shape flatness measuring rolls, one for the entry and one for the exit side. These measuring rolls are characterized by a very sturdy design, excellent measuring precision and failure-free signal transmission.

Also included in the supply are fluid and media systems, such as high and low-pressure hydraulics and the emulsion plant, which comprises a selective spraying system for roll cooling and a separate spray header for roll gap lubrication. The mill will also be equipped with COANDA nozzles at the mill entry and exit, which will ensure most efficient removal of coolant.

The SMS group is a group of companies internationally active in plant construction and mechanical engineering for the steel and nonferrous metals industry. Its 14,000 employees generate sales of over EUR 3.3 bn.
